MACHINE FOR MAKDN'G WIRE FABRIC.

Application filed May 11,

T 0 all whom z' may concern:

Be it known that we, HERBERT E. WHITE and THOMAS H. KANE, citizens ofthe United States, residing at Youngstown, in the county of Mahoning andState of Ohio, have invented certain new and useful Improvements inMachines for Making Wire *abric, of which the following is aspecification.

lThis invention relates to wire working, and more particularly to animprovement in machines for making wire mesh reinforcementof the typeused in building concrete roads.

To that end the invention contemplates a novel mechanism, andassociation of instrumentalities, so designed and organized as toprovide a practical and reliable machine having means for handling theline wires and the cross wires in a manner to automatically assemblethem accurately and uniformly in position to be joined or con-- nected,thereby rendering the machine capable of producing wire mesh of astandard construction, and also in large quantities at sufficient speedfor a large commercial out- A further and more specific object of theinvention is to provide a novel stapling or tie-forming unit, forinsuring the proper connection between the line wires and the crosswires of the fabric or fmesli In that connection it is proposed toprovide a unit which may be duplicated as desired and of a constructionpermitting standardization of parts, at the same time making it possible`,to utilize any desired number of units in alined relation to produce afabric of the desired width. It is, therefore, one of the distinctivefeatures of the invention to provide a stapling or connectingunit foreach of the line wires, the same being so designed and equipped as tofacilitate the passage of the line wire through the machine, while atthe same time assist- I, ing in the handling and manipulation of thestaple or tie preparatory to its -final clinching about the cross wire,thereby connecting the latter to the line wire.

The invention also has for its object a 1922. serial No. 566,177.

novel consolidation of the and the means for making cross-wires, wherebytie-forming unit,

and feeding. the the latter in proper cut lengths, and pre-straightened,will be fed singly to position against the line wires at the proper timeand in the proper spacing for being fastened to the line wires by theclincher-action of the fabricating unit. In that phase of the invention,the latter also contemplates the employment of a cross-wire making andfeeding unit having a large producing capacity and adequate means forfeeding the Asingle wires at the desired Speeds..

l.A further object of the invention is to provide a simple and practicalarrangement of auxiliary devices for, feeding and handling the line andcross wires in proper synchronism with the operation of the staplingunits.

With the abovevand other objects in view which will morereadily appearas the nature of the invention is better understood, the same consistsin the novel construction, combination7 and arrangement of partshereinafter more Afully described, illustrated and claimed. y y

A preferred and practical embodiment of the invention is shown in theaccompanying drawings, in which:

lin the making of wire fabric or wire mesh of the type used in thereinforcement of concrete roads, it is desirable to utilize line wiresof relatively heavy.gauge to be embedded lwithin the road bed and heldin proper spaced relation by a series of transversely disposed crosswires, and it is the purpose of the present invention to provide amachine with adequate facilities for producing a wire mesh fabric ofthis type in commercial quantities. lfn that connection it is proposedto provide a novel assembly of devices for handling the wires, and novelmeans for connecting or joining the same in a thoroughly rigid andpractical -manner to insure the proper spacing thereof from the time ofmanufacture until placed in the road bed for use. rllhe type of wiremesh referred to is shown in Figure 11, the saine comprising therelatively heavy line wires W and the lighter cross wires W joined attheir intersections by the clinched staples S.

llt will be observed from Figure 1 of the drawings, that a machine ofthe type referred to primarily includes in its organization a novelfabricating unit designated generally by the letter A and whichfabricating unit includes those instrumentalities which provide forfeeding the line wires and the cross-wires into. proper crossingrelation,

l and the means for positioning a staple at the intersection of the linewire and the crosswire and clinching the same about the two, therebyedecting a fastening or union, at

each point of intersection. Also the inachine includes in itsorganization a suitable feeding device B for the line wires, and-across-wire supplying unit C having means for making and feeding thecross-wires to the fabricating unit in single order at the requiredintervals. Suitable operating connections are provided between thefabricating unit and the cross-wire unit to eect the operation of theseunits in unison and proper synchronism` thereby to obtain acrecentecuracy and reliability in the correlated functions.

Considering first that part of the machine embodying the fabricatingunit A, it will be noted that the same includes the particularinstrumentalities which function to intermittently assemble the line andcross wires and place the fastening staples thereover whereby the legsof the staples may be finally clinched about the cross-wires to completethe joint. These instrumentalities consist principally of the feedingdevice B for the line wires, the staple carrier 1, staple plunger die 2,anvil clinching die 3, and the cross-wire carrier a. llihe manner inwhich they are preferably arranged in a machine organization is clearlyshown in Figures 1, 2 and 3 of the drawings, and will now be moreparticularly referred to, the description of the details of each beinghereinafter more fully set forth.

'llhe upper and lower dies 2 and 3 which have been respectivelydesignated as the staple-plunger die and the anvil-clinching diev arecarried by the oppositely working jaw members 5 and 6 mounted toreciprocate in the frame F of the machine. The upper jaw 5 may besuspended by the links 7 from the lever arms 8 on the shaft 9; and, asshown in Figure 2, this shaft may also be equipped with the od-set crankarm 10. Said crank arm is disposed at an angle to the arms 8 and ispivotally connected as at 11 with the reciprocatory rod 12 whose lowerend is also pivotally connected, as at 13, with theV rocker lever 1elocated at the bottom of the frame F.

'llhe lever 14 above referred to may be ro-ckably supported as at 15 andpreferably carries on one face thereof the spaced oppositely disposedbearing rollers 16 adapted to be engaged by an operating cam 17 on the.main actuating shaft 18 suitably journalled in the lower part of theframe. 1n addition to carrying the operating cam 17, this shaft 18 alsocarries the eccentrics 19 adapted to receive the bearings 20 of thesupporting or connecting rod element 21 which pivtally engages as at 22with the lower jaw 6. For the purpose of operating the said actuatingshaft any suitable and convenient means may be utilized, such forinstance as the driving sprocket 23 and chain 2t, as shown in Figure 1.

'llhe jaws 5 and 6 which carry the fabricating instrumentalities 2 and 3heretofore referred to may be of any required length in orderl to makethe desired width of finished fabric, and, for the purpose of properlyfeeding the line wires W between the jaws to insure accuracy ofoperation in connecting the line wires and the cross wires a checkdevice D may be employed at the feeding-in side of the fabricating unitA, as shown in Figure 2. rJlhis check device permits the intermittentadvance of the line wires upon the forward reciprocating movement of thefeeding device B after the same leave the rolls E of the straighteningunit G, and prevents backward or retrograde movement of the line wiresupon the backward stroke of the'feeding device. After passing throughthe checkdevice D, and issuing from the guide D thereof the line wires Ware delivered into the zone of action of the fabricating unit A whichconnects the cross wires W therewith.

In connection with the delivery of the cross wires W to the fabricatingunit from the cross wire supplying unit C, it may be observed that thecross wire carrier 4 previously referred to may be in the form of ashiftable carrier arm 25 h-aving thel slotted end portion 26 slidablyengaging over the shaft 27 while its oppositev end pivotally connects asat 28 with a swinging throw link 29. This throw link 29 is pivotallysupported at its lower end 30 on the base part of the machine, thusproducing in effect a toggle 25-,-29 which operates to give the crosswirecarrier the necessary upward swinging movement, whereby the crosswire W resting in the cradle. formed by the olfset or projection 31 ofthe arm 25 will be delivered in position above the anvil clinching die 3so that as the latter rises itz will` firmly place and hold the crosswire in position against the line. wire during the operation ofclinching the ends of the staples.l y

As previously set forth, the fabricating unit A includes the tie formingor clinching means which essentially consists of the staple carrier 1,staplei plunger die 2 and the anvil clinching die 3 all of whichcooperate to place the staple astride the crossing points of the lineand cross wires, automatically, and subsequently effect the complete andsecure union between the wires ,by upsetting the ends of the staple onthe anvil die and clinching the sanie abou-t the cross wires while thebight of the staple embraces the line wire.

Referring first to the structural fea-tures and characteristic of thestaple carrier 1, it may be observed that the same constitutes a part of'a staple magazine (not shown) and serves to deliver the staples insingle order to the upper die 2 at proper intervals during thefabricating operation. As will be observed from Figure 4 for example,the said staple carrier may consist of a rela- -tively shiftable andyieldably mounted body the shoe 32 to be normally pressed forwardagainst the face of the reciprocating stapleplunger die 2, vand yetpermits of the same being readily forced backward upon the descent ofthe plunger to insure of one of the staples S being carried downwardlytherewith. The upper part of lthe body of the staple carrier ispreferably provided with an inclined carrier bar 36 upon which thestaples are hung whereby they may slide downwardly by gravity onto thedelivery section 37 which is preferably formed into the curved orarc-shaped formation shown and' is of such cross sectional design as toreduce the friction on the traveling staple after it leaves the mainpart of the bar 36. That is' to' say, as the delivery section 37approaches the horizontal plane it is preferable to eliminate as muchresistance or friction as possible .to permit the free sliding of thestaple toward the die 2 so as to insure the proper feed of the staplesthereto.

Therefore, as will be observed from Figures 4, 8, and 9, the ysaiddelivery section 37 of the carrier bar has its side walls grooved orcut-away to provide in effect the spaced guiding beads 38 at the sidesof the section whichvolfer a comparatively small area of contact orengagement for the sides or legs of the staple while the top edge or.corners of the rib are also cut-away so as to leave only a single topbead 39, thereby reducing the area of contact between the top of thesection and the bight or loop end of the sta le. Beneath the eXtreme endof the part 3 the end of the basel of the carrier is provided with thestaple clearance notches 40 and the upper corners of the base at eachside'of the notches is formed with the inclined plunger die engagingshoulders 41 for permitting the free descent of the plunger 2 when theshoulders 42 thereof engage with the carrier and shift it horizontallyout of the way.

The inclined die shoulders 42 on the staple plunger die 2, are locatedon the relativelyA separate spring legs 43 which are cut away at their.lower inner ends to provide a relatively flaring line `wire receivingmouth 44 and line wire receiving recess 45, while the face of theplunger, between the shoulders 42 may be formed with a substantiallyarched recess constituting a staple receiving seat 46. This seat as wellas the shoulders 42 may be duplicated on both faces of the die to permitof the reversing thereof when desired.-

' The upper end of the plunger die 2 may be secured in any suitable andconvenient manner to the upper jaw 5 of the machine, and for the purposeof varying the spacing of the legs43 thereof to regulate the width ofthe line wire receiving recess 45 and the staple seat 46, and alsotdcompress the legs to grip lthe stapleafter it leaves the magazine, thelower ends of the legs 43 pass between the compression heads H of theadjusting or tensioning devices 47 which may be of the nut and screwtype shown in lFigure 7 of the drawings.

rllhe anvil die 3 which cooperates with the plunger die 2 to clinch thelegs of the staples S to the cross wires W may be carried by the lowerjaw 6 in any suitable and convenient manner, as for example, by theclamping bar 48 and the wedge lock 49. As will be seen from the assemblyshown in Figure 4 the said die preferably fits into a socket 50 formedbetween the bar and the jaw 6, and

the latter, at one side of the die is provided receiving groove and in alower plane. At

each end of the cross wire receiving groove 53 the die head is formedwiththe clinching y grooves 54 which lie in a plane below the bottom ofthe groo-ve 53 and receive and direct upwardly the lower ends of thestaples S which are preferably bent slightly before being placed in themagazine to insure the curling up thereof about the cross wires as theplunger die and anvil die complete their opposing strokes. rllhe rearedge of the die 3 is also provided with the upwardly inclined face 55for. assisting in the delivery of the cross wire into the groove 53 bythe cross wire carrier 4. The arrangement of grooves described in thehead of the die 3 is such that the groove 53 for the .cross wire permitsthe same to be carried in a plane below the line wire, but above theplane of the grooves 54 for guiding the legs of the staples intoclinched engagement with the cross wire, thereby insuring the up-settingor clinching of the legs of the staples about the cross wires while theweb or bight of the cable straddles the line wire.

'llhe general operation of the fabricating machine is substantially asfollows rlhe main or line wires W which are rela- .tively heavy gaugeare fed into the fabricating unit A intermittently by the reciprocab ingfeeding device B, and are prevented from being withdrawn by means of thecheck device D. rllhis feeding-in of the main or line wires takes placewhile the jaws 5 and 6 are retracted, and consequently while thestapling plunger 2 is elevated above the anvil die 3, When the staplingplunger 2 is elevated to the proper point the staple receiving seat 46thereof registers with the end of the section 37 of the staple carrier 1in such a way thatthe leading staple Moenia thereon slides into the seat46, and then as the stapling plunger 2 begins to move downwardly theshoulders 42 on the plunger engage with the ,inclined shoulders 41 onthe carrier to push the carrier back out of the way, thereby entirelyfreeing the leading staple from the carrier and carrying it in the Seat46. As the plunger 2 continues to move down, the spring legs 43 areforced together by the compression heads 4 to thus push the staple inthe seat 46 and prevent its falling out during the continued downwardmovement. e

ln the meantime, when the lower end of the plunger 2 passes the upperend of the die 3 carried by the lower jaw 6 the cross wire carrier 4delivers one of the cross wires W over the inclined edge l55 of the die3, across the top of the groove 52,and into the cross wire receivinggroove 53. Because of the overlapped relation of the plunger 2 andthevdie 3 the cross wire ll] will be safely positioned in the groove 53,and when the plunger reaches the limit of its downward movement the die3 will move upwardly toward the line wire and the clinching grooves 54will bend lower ends of the Staples legs about the cross wire W. rll`huswhen the staple is fully curled about the cross wire W as shown inFigure 4, the said cross wire is united with the main or line wire W ina thoroughly practical and secure manner. When the joint thus formed iscompleted the jaws 5 and 6 recede carrying therewith the plunger 2 andanvil die 3, until the plunger die and anvil die reach the limit oftheir backward strokes, whereupon the anvil die 3 will be ready for thenext operation to receive the cross wire `W, while the plunger die 2will permit the staple carrier l to slide forwardly again to enable theleading staple on the section 37 to be placed in position to gravitateinto the staple receiving seat 46, in the manner already explained. Asthe staple carrier l is adapted to carry an adequate supply of stapleson the bar 36 the quantity of staples will always be sufficient to meetthe demands of the fabricating operation.

llfhile any suitable and convenient form ofmachine may be used for.making and feeding the cross wires to the fabricating unit, the type ofcross wire supplying device C 'shown in Figures l and 10 of the drawingsmay be conveniently utilized. rllhis device includes in its organizationa suitable frame 56 having mounted thereon the wire cutting andstraightening device 57. These devices may be of a standard commercialtype obtainable .on the open market, and no claim thereto is made in thepresent case, the same being simply illustrated in more or lessdiagrammatic form and only to illustrate one way of making andstraightening the cross wires for delivery-onto the ini clined conveyortables 58 which may consist of a plurality of spaced inclined invertedT- rails or equivalent bars. As will be observed from Figure 1, the saidinverted T-bars which constitute the conveyor tables 58 incline towardeach other and have arranged therebetween a check and alining partition59, the same being provided with the alining recesses or grooves 60 inopposite sides thereof and having a segregating gate or head portion 61projecting qinto the delivery throatl 62 of the magazine chute 63. Thedescribed arrangement of the check partition 59 has the advantage ofarresting or,

checking the cut lengths of cross wire at the end of their descent downthe inclined feeding tables, and causes the same to straighten or Aalinewith the runway or passage of the delivery chute 63, thereby preventingjamming or clogging of the wires at the entrance of the chute andpermitting them to be stacked in single order therein, as shown inFigure 10.

From the delivery chute 63 the wires are removed individually by meansof a delivery roll 64, the same having a plurality of spacedlongitudinal grooves or pockets 6 5 formed in'its circumference forregistering at intervals during the cycle of rotation thereof with theend of the delivery chute 63 to receive a single cross wire and carry itthrough an arc of substantially 180 for deposit on the upper flight ofthe horizontally disposed conveyor 66. rlhe periphery of the deliveryroll 64 has a relatively snug fit with the hood or casing 64, thereby toinsure the cross wires W remaining in the pockets 65 during the,rotation of the roll from the point where it receives the wire, to thepoint where it discharges onto the conveyor 66, and, to insure that thewires will not shift longitudinally out of the pockets 65 before theproper time for delivery a suitable end guard 67 may be employed. 0n

the other hand, to compel delivery at the proper point a stripper blade68 may be arranged at such a point that its stripping edge 69 willintersect the circumferential plane of the roll 64 and extend inwardlyto a sufficient point as at 70 to reach behind the position occupied byone of the cross wires W in one of the pockets and forcibly eject thesame as it is brought around to discharging position.

lAfter the cross wires are deposited in single order on the upper Hightof the horizontal conveyor 66, they are advanced to a y, point wherethey are picked up' by the carrier strip 71 of the upwardlyincliningconveyor 72,- and this conveyor, in turn, feeds the wires in singleorder to the delivery conveyor 7 3 which -deposits the cross wires onthe cradle projections 31 vof the cross wire carrier 4. As( will also beobserved from Figure lthe conveyors 66, 72 and 73 may the' pulley 94 ofthe conveyor 83.

tion 74 which passes over the pulley 75 of the main driving unit 23 anda pulley 76 on one of the conveyorsupporting shafts 77. The deliveryroll 64 may also derive its power from the conveyor 66 by the chain orequivalent connection 78.

From the foregoing it will be apparent that the arrangement describedprovides simple and practical means for maintaining an adequate supplyof pre-cut and pre-straightened cross wires for delivery to thefabricating unit A. However, by way of illustrating the range ofmodification that may be resorted to-in the construction of the crosswire supplying unit to obtain increased capacity therefor, reference maybe made to Figure 12 of the drawings, wherein it will be observed thatthe type of cross wire supplying unit C' shown in that ligure consistsof a battery of cutting and straightening machines 8O arranged at thetop of a magazine column 81 having therein a vertical magazine chute V82which provides materially increased storage capacity for the pre-cut andpre-straightened wires. This magazine chute 82 corresponds in functionto the chute 63 in the device C and the 'wires are individually removedtherefrom by thedelivery roll 83 which may be provided with the guardand stripper elements 84 and 85 to insure the delivery wires in singleorder to the horizontal receiving belt or apron 83a. In this form ofembodiment the roll 84 may be driven by the gear 86 which meshes with ashiftable clutch pinion 87 slidably carried by an operating shaft 88 andadapted to be thrown into and out of engagement with the gear 86 throughthe medium of the clutch lever 89. When it is desired to use only oneunit, the clutches-of all of the remaining units may be opened or thrownout, thereby permitting all except one unit to idle, or on the otherhand when an increased capacity is desired all of the clutches may bethrown in thereby -causing all of the' units -to operate and provide anaugmented number of cross wires for delivery to the fabricatingmechanism.

The operating shaft 884 may carryat one end thereof a driving gear 90adapted to mesh with a driving pinion 91 actuated by the pulley and beltconnection 92-93 from pulley 94 may be .driven by belt or chain 95, andthe cross wires supplied to the upper flight of the belt 83*1 may bepicked up by ythe upwardly traveling Hight of the conveyor 96 to be fedto the delivery conveyor 7 3a which performs the same functlon withrespect to the cross wire carrier ,4 that the This conveyor 73 doesjinthe construction shown, i

in Figure 1.

12, wherein each of the cross Wire The multiple unit embodiment ofFigure i and cutting units is individually controlled enables theoperator to meet any requirements as to speed of fabrication, supplyinga few, or as many cross wire lengths as the particular operation callsfor.

Without further description itis thought that the features andadvantages of the present improvement will be readily apparent, and itwill of course be understood by those skilled in the art, that changesin the form, proportion, and minor details of construction may beresorted to, without departing from the spirit of the invention, orscope of the appended claims.
